ABSTRACT:
A mobile telephone terminal powered by a battery, which terminal is mainly comprised of a processor unit and a logic LSI unit as a control part thereof. The processor unit handles first control functions which are not used frequently but which are complicated and operate at a high clock speed. The logic LSI unit handles second control functions which are used constantly and frequently at a low clock speed. The processor unit is activated intermittently on demand by the logic LSI unit and thereby reduces power consumption.
